The short and long-term impact of the healthy kids initiative on depressed mood in youth living with obesity
Bibliographic record
Abstract
PURPOSE: The purpose of this study is to determine the effect of a free, comprehensive program with social support on depressed mood in youth (aged 11-17 years) living with obesity in a prospective, longitudinal, community-based study. METHODS: Youth living with obesity (BMI > 30), residing in three cities in Saskatchewan, Canada, were eligible to participate in a 12-week program designed to facilitate behavioural change with five physical activity sessions a week, one dietary session a week, and one group cognitive behavioural session per week offered by health care professionals. Baseline data were collected on depressed mood (Centre for Epidemiological Studies-Depression 12 or CES-D 12), health-related quality of life (SF-12), and self-esteem (NLSCY) at baseline, 12-weeks, and at 52-weeks RESULTS: Overall, 2598 youth started and 2292 (88.2 %) completed the 12-week program with 1703 (74.3 %) of participants presenting for 52-week follow-up. Depressed mood improved significantly over the course of the program: 79.2 % of participants had depressed mood at the start of the program and this decreased to 64.7 % at the end of 12-weeks; which was an overall relative reduction of 18.4 % (Cohen's d = 0.94). The mean CES-D 12 score at one-year was significantly lower than the mean baseline score (17.90 compared to 21.11, p < .001). By depressed mood severity, 58.7 % of participants had severe depressed mood at baseline, which reduced to 31.6 % at 12 weeks, and 27.9 % at 52 weeks. Age and maternal occupation were initially significantly associated with depressed mood at 52-week follow-up (unadjusted). However, after binary logistic regression was used to determine the independent risk factors for having depressed mood at 52-week follow up, only older age (OR 1.88, 95 % CI 1.52-2.34, p < .001) was significant. CONCLUSION: The Healthy Kids Initiative lends more evidence that healthy behavioural interventions can have a positive impact on depressed mood among youth living with obesity.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
